We look at the division of 28435070 by 375 
The aim is to understand the frequency of 375 in 28435070.

Step 1:
If we divide 2 by 375, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 375

Advancing to step 2:
375 goes into 28 0 times with a remainder of 28.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Bring next digit (4) of the dividend behind the 28 and repeat the process: 284 / 375

Step 3:
The number 375 fits into 284 0 times, leaving a remainder of 284.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 284 to get 284.
Bring next digit (3) of the dividend behind the 284 and repeat the process: 2843 / 375

Moving on to step 4:
375 can be fit into 2843 7 times, resulting in a remainder of 218.
The next digit of our result is 7. 
Result so far: 7.0
Subtract 2625 from 2843 to get 218.
Fetch the next digit (5) from the dividend, attach it to 218 and continue: 2185 / 375

Step 5:
375 can be fit into 2185 5 times, resulting in a remainder of 310.
Put 5 as the next digit of the answer. 
Result so far: 75.0
If we take 1875 away from 2185, we end up with 310.
Append the next digit (0) from the dividend to 310 and continue with: 3100 / 375

Step 6:
375 can be fit into 3100 8 times, resulting in a remainder of 100.
The number 8 becomes the next digit in our result. 
Result so far: 758.0
Subtracting 3000 from 3100 leaves us with 100.
Grab the next digit (7) from the dividend, add it to 100, then carry on: 1007 / 375

Going ahead to step 7:
375 goes into 1007 2 times with a remainder of 257.
The number 2 becomes the next digit in our result. 
Result so far: 7582.0
The remainder is 257 after subtracting 750 from 1007.
Append the next digit (0) from the dividend to 257 and continue with: 2570 / 375

Going ahead to step 8:
If we divide 2570 by 375, we get 6 and a remainder of 320.
Use 6 as the next digit of our solution. 
Result so far: 75826.0
Subtract 2250 from 2570 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 9:
3200 divided by 375 is 8 with a remainder of 200.
Use 8 as the next digit of our solution. 
Result so far: 75826.8
Subtracting 3000 from 3200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 10:
375 goes into 2000 5 times with a remainder of 125.
The number 5 becomes the next digit in our result. 
Result so far: 75826.85
The remainder is 125 after subtracting 1875 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Going ahead to step 11:
375 can be fit into 1250 3 times, resulting in a remainder of 125.
Record the quotient 3 as the next digit in the result. 
Result so far: 75826.853
The remainder is 125 after subtracting 1125 from 1250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Step 12:
When dividing 1250 by 375, we get 3 with a remainder of 125.
The next digit of our result is 3. 
Result so far: 75826.8533
If we take 1125 away from 1250, we end up with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

The final outcome is 75826.8533, with a leftover of 0.00125.
